摘　　要：GIS系统在边坡稳定性分析中的应用越来越受到重视。以布沼坝露天边坡岩体力学参数、降雨量等6个因素为基础,利用模糊综合评判的原理,将GIS强大的数据处理和空间分析功能应用到露天矿边坡危险区域的等级划分,提出了利用模糊综合评判的方法,基于GIS的边坡危险区域等级划分的理论方法,由此可以区划出整个边坡岩体不同区域的安全度;考虑影响因素多,安全度评价结果用颜色分区更直观,弥补极限平衡方法分析边坡稳定性中的不足,为工程区域治理范围提供决策依据。GIS is becoming increasingly important in slope stability analysis.Based on the six factors such as rock mechanical parameters and rainfall,this article classifies the slope hazardous areas using the principle of fuzzy comprehensive evaluation together with the data processing and spatial analysis functions based on GIS.The theory of hazardous area classification based on GIS is proposed through the method of fuzzy comprehensive evaluation.Finally,the slope safety in different regions is classified.Taking many factors into account,the area of showing safety evaluation results is more intuitive with different color,making up for the shortcomings of slope stability analysis with the limit equilibrium method.It provides a basis for decision making of slop governance range.
